In contrast to the MIT Intrinsic Images dataset , Bell et al. introduce a much larger dataset of more realistic scenes. The ground truth was obtained using crowdsourcing. In addition, they present a new intrinsic image algorithm and include thorough comparison to several recent approaches: Garces et al. , Zhao et al.  and Shen et al. . The dataset can be downloaded online at opensurfaces.cs.cornell.edu/publications/intrinsic/ and the source code is available on GitHub.
